Activity 1.Extensive readingActivity 2 Intensive ReadingNumber the puzzlepieces in order according to how Darwin generated the Theory of Evolution.1. On his journeyDarwin studied _He noticed that some species of animals were _ various living things in their natural environments and samples of the plants and animals he had collected.very similar to each other2. Generate ideasDarwin asked the questions: l How did different species _l _come to existMaybe animals evolved as they adapted to their changing environmentsPara 2. The young man in question, Charles Darwin, was a geologist and naturalist, fascinated by rocks, plants and animals. He left England on the ship, the Beagle, in 1831. The journey gave him the chance to study various living things in their natural environment. After Darwin had spent some time in South America, his room on the ship was crowded with samples of the plants and animals he had collected. As he studied these, he asked himself the question: how did different species come to exist?Para 3. At that time, people believed that all species had appeared on Earth a the same time, and had not changed since. But Darwin began to think differently. He noticed that some species of animals were very similar to each other. Maybe animals evolved as they adapted to their changing environment? It was just an idea, but enough to inspire Darwin to look for more evidence.Para 2. The young man in question, Charles Darwin, was a geologist and naturalist, fascinated by rocks, plants and animals.

When the Beagle reached the Galapagos Islands in 1835, Darwin saw a variety of new species, but it was the birds that interested him the most. Darwin noticed that there was a difference between the finches on each of the islands. It seemed their beaks had evolved according to what food was available on that particular island.3. Look for more evidence He noticed_ It seemed the beaks_.that there was a difference between the finches on each of the islands. had evolved according to what food was available on that particular islandPara5. Darwin suspected that the finches had evolved from a common ancestor, which had arrived on the islands a long time before. Over time, it had slowly evolved into many new species. And that was the answer to how new species of plants and animals came to exist: they evolved from earlier ancestors.4. Develop ideasDarwin suspected that the finches _and it had_ had evolved from a common ancestor, which had arrived on the islands a long time beforeslowly evolved into many new speciesPara6. It was a completely new ideaa theory of evolution. Darwin explained this theory in his book, On the Origin of Species. It was not published until 1859 and immediately caused a storm. Many people refused to believe that living things, including humans, had evolved from lower forms of life. They were shocked. But Darwins scientific studies were so convincing that more and more people started to believe his theory.5.

Think & Share1)Work in pairs. Suppose you are in an interview program “Talk with Celebrities”, one student is the interviewer , and the other one is “Darwin”.Act out an interview with the “Darwin” about his journey of discovery.Tips: you may use the following questions. What did you find on your journey. How did you solve your puzzles. Talk with CelebritiesTalk with CelebritiesTalk with CelebritiesTalk with Celebrities Activity3. Think & Share2)What have you learnt about the spirit of scientific exploration? How can this spirit help you in your life and studies?Scientific discoveries are based on the research and the evidence.The scientific exploration may take quite a long time and great efforts, courage and determination to achieve. ？hard workperseveranceendurancebraverySelf-beliefinterestcourage How can this spirit help you in your life and studies? I can succeed in science, the most important thing is the love of science and insisting onlong- term exploration. -Charles Robert DarwinHomeworkWrite a Passage “The man I admire most- Charles Darwin” Tips: You may use some useful expressions in the passage
